Experiment study of total anthraquinone in cassiae semen on lipid peroxidation and PPAR-gamma expression in liver tissues of rats with alcoholic fatty liver / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of total anthraquinone in Cassiae Semen on lipid peroxidation and peroxisome proliferator activated receptors gamma (PPAR-gamma) expression in liver tissues of rats with alcoholic fatty liver.</p><p><b>METHOD</b>Referring to literature, it was established animal models of fatty liver feeding with alcohol. Rats were randomized into 6 groups, except the normal group, the other 5 groups of rats had been administered alcohol two times a day for 3 months. Rats were killed at the end of this experiment. It were respectively measured that the contents of ALT, AST, AKP, TG, TC, HDL-C, LDL-C, MDA, SOD, FFA in the serum and TG, TC, MDA, SOD, HL, LPL, FFA in the liver. The left leaf of liver was observed by histopathological staining, the immunohistochemical staining and RT-PCR were used to observe the effects on the expressions of PPAR-gamma mRNA.</p><p><b>RESULT</b>Compared with the model group, total anthraquinone in Cassiae Semen could remarkably decrease the content of ALT, AST, TC, TG, MDA and increase the content of SOD in the serum of the experimental fatty liver induced by alcohol; remarkably decrease the content of TC, TG, FFA and increase the content of HL, LPL, SOD in the liver of the experimental fatty liver with induced by alcohol. Total anthraquinone in Cassiae Semen group was the similar the model group, but remarkably lighten inflammatory cell intiltration and fibrosis increasing. The RT-PCR and immunohistochemical staining results showed that compared with the normal group,the model group could remarkably decrease the expression of PPAR-gamma mRNA in the liver (P < 0.01). Compared with the model group, total anthraquinone in Cassiae Semen could remarkably increase the expression of PPAR-gamma mRNA in the liver of the experimental fatty liver (P < 0.01).</p><p><b>CONCLUSION</b>The results showed that total anthraquinone in Cassiae Semen has good effects on the treatment of hepatic fat induced by alcohol diet in rats. the possible action mechanism of total anthraquinone in Cassiae Semen possess obvious effect of regulating the disorder of lipid metabolism, ameliorating hepatic function, as well as anti-lipidperoxidation, increasing the expression of PPAR-gamma in hepatic cells of rats.</p>
